Turning Ideas into Engineered Solutions Aftermarket Bearings for Tunnel Boring Machines Slewing ring bearings in a tunnel boring machine are subject to tremendous wear and abuse, and most need replacing regularly. But frequent purchases of OEM bearings at OEM prices put a strain on any operating budget. Now Kaydon offers you two ways to save money without compromising performance — by manufacturing new replacement bearings, or remanufacturing your worn bearings. Both methods result in top-quality slewing rings that meet your performance requirements at substantial savings. New Replacement Kaydon Corporation Bearings Division can make a replacement for any slewing ring bearing, regardless of OEM. We have a comprehensive reverse-engineering capability and three manufacturing plants, all certified for ISO 9001:2000. Every project begins with a thorough inspection and NDT evaluation of the customer’s slewing ring. The part then undergoes engineering evaluation, which often yields design improvements that will not affect interchangeability. Remanufactured Remanufacturing is not a sideline for Kaydon, but a dedicated program with its own personnel, equipment and inventory. All remanufactured bearings come with a warranty equal to a new bearing. Highlights include: free inspection and noobligation evaluation engineering review and recommendations raceways precision-ground to proper geometry and load capacity replace separators and lubricant
